You should add dynamic controls in Page_Load or Page_Int events. You are trying to add dymic controls in LoadViewState method by caling getcontrol() method. Try to avoid it. It may cause the error.

            tabcontainer1_ActiveTabChanged(tabcontainer1, null);
            getcontrol();
        }        

    }
    protected void Page_Init(object sender,EventArgs e)
    {      
            getcontrol();
    }

    {

    }
    public void getcontrol()
    {
        AjaxControlToolkit.TabPanel thepanel = new AjaxControlToolkit.TabPanel();
        thepanel.ID = "tabpanel1";
        thepanel.HeaderText = "General";
        tabcontainer1.Controls.Add(thepanel);
        PlaceHolder ph1 = new PlaceHolder();
        thepanel.Controls.Add(thepanel);
